PHP parsing a line from within a Json API page - php

Question

I am trying to convert this script over from finding one set of variables eg(playtime_forever) to finding another variable eg(backpack_value)
if (!empty($data->response->games)) {
foreach ($data->response->games as $game) {
if ($game->appid == $game_id) {
$playtime = $game->playtime_forever;
if (($playtime < 5940) && ($playtime > 1)) {
$fh = fopen("final.".$timestamp.".txt", 'a') or die("Can't open file");
...
The page it originally parsed looked like this
http://pastebin.com/rnnCsijd
but will now be this. Pulled from here
http://backpack.tf/api/IGetUsers/v2/?&steamids=76561197992146126&format=json%27;
{
"response": {
"success": 1,
"current_time": 1369669066,
"players": {
"0": {
"steamid": "76561197992146126",
"success": 1,
"backpack_value": 36412.71,
"backpack_update": 1369630863,
"name": ":HIT: Bobo the Monkey Boy",
"notifications": 0
}
}
}
}
A small change but I am unable to make the script do what I want. If you could explain how to go about this and the steps behind it, it would be great. I have been trying for a while but I am unable to finish the script

To get the profiles as per your comment, use this code:
$profiles = array(); //init array so we can use $profiles[] later
$limitValue = 1000; //Limit value of backpack_value
foreach($data->response->players as $player) { // Loop thrugh all the players
if ($player->backpack_value < $limitValue) { // Check the backpack_value
$profiles[] = $player; // Assign the required players to a new array
}
}
var_dump($profiles); // Dump the array to browser for debugning
